TUBING ROLLER.

i Application led lMay 317 1927, Serial No; 195,385.

This invention hasto'ido with a tubing roller and hasfpart-icular reference toa device useful for rolling boiler tubes, yor the y like, to make them tight in a boiler plate, or drum. y

The tool provided by this invention is useful, generally, for rolling boiler tubes, or the like, and is particularly suited for use where the tubes are in one side of a cylindrical drinn, or the like, and the tool must be passed through small openings in the opposite side of the drum to reach the tubes. Tubes connected into-a cylindrical drum, or the like, as above mentioned, Work loosefrom'ftime to time, making it necessary for them to'be rerolled ortightened. As a result of this condition, some of the tubes are rolled more than others so that the insidediameters of the tubes vary. Under the practice generally followed, it is necessary to use several different sized rolling tools to meet this variation in the tubes. This handling of .several dierent sized rolling tools notonly involves the expense incidental to having several tools, but consumes considerable time in obtaining the properv size tool for a given tube and often results in the smaller size tools being forced beyond their limit. r

It is an object of this invention to provide a tube rolling device which will operate effectively in tubes of various internal diameters so that a single tool will satisfactorily meet the conditions above referred to.

It is another object'of this invention to provide a tube lroller which is simple,r effective and durable in construction.

The various objects and features ofthe invention will be best and more 'fully understood from the following detailed description of a typical form and'application of the invention, throughout which description ref-V erence is had to the accompanying drawings, inwhich: 'n

Fig. 1 is a view illustrating thev rolling tool provided by this invention in operating position in a tube;

Fig. 2.is a longitudinal, lsectional view ofr the rolling tool Vshowing it in the collapsed position;

Fig. 3 is a transverse, sectional view, taken as indicated by line 8-3 on Fig. 2;

Fig. 4 is a view similar to Fig. 2, showing the tool in the expanded position; and

Fig. 5 is a transverse, sectional View, taken as indicated by line 5-5 of Fig. 4.

The tool provided by this invention in- I cludes, enerally, an annular body 10, a plu-f rality o rollers V11, carriers 12 for the roll-V ers, mounting means 13 connecting'the roller y carriers 12 with the body 10, and an operating mandrel 14. l y

The body 10 is. an annular or ringshaped member which serves as a mounting or carrier `for the roller carriers 12. The outside diameter of the body 10- is suoli as to allow the body to be freely passed through a holey such as may occur 1n a kboiler plate. or ldrum opposite` the tube tobe rolled. The inside diameter of the body, that is, the openinginthe body, is made to properly pass or accommodate yan operating mandrel. As 1 far as this invention is concerned'anylsuitable op erating means or mandrel may be used to operate the tool. v y f. I' In accordance with the present invention,

rollers and rollercarriers. In the drawings, we have, for purpose of exampledisclosed a form of the' invention including three roller carriers 172.l Each carrier 12 .is arcuate or segmental 1n formfand has a socket v16 formed in it from its inner lend to carry. a

roller 11. The rollers'11` are, of course,

round in cross section and the sockets in the l'Ans the tool may be provided with: a plurality ot Y ness of the carriers and the sockets 16 are formed in the carriers so that the rollers project from the inner and outer sidesof the carriers, as clearly shown in Fig. 5 of the drawings. In the preferred construction, the sockets kare pitched or inclined slightly from a position parallel with the longitudinal axis ofthe tool, as shownin Figs. 1 and 5 of the drawings. Further, vthe rollers are preferablytapered slighly to correspond to the taper ofthe operatin i mandrel so that they engage the tube uni their length.

vThe mounting means, 13 provided by this invention connects the carriers 12 withv the body 10 so that theyare independently movable radially with reference to the body. Each carrier 12 is provided at its innerend with an enlargement or head 20 provided with a recess 21 to receive a lug 22 projectinv from the side of the body 10. A mounting pin 23 is carried by the head 20 to exform ofthe invention shown in the draw-V ormly throughout eine!! ings, the pin 28 is tightly carried by the head 2O and tits more or less iireely through the opening 24rin the lug 22. For the purpose ot allowing` the desiredvradial movement of the carrier with reference to the body, the opening f-l in the lug is made in the form oit a radially disposed slot which allows the pin to move between the positions shownin Figs. 2 and ll ot the drawings. The heads ot the carriers slidably engage the body 10 so that the carriers are braced by the body.

The enlargements or heads 20 at the inner ends of the carriers 12 project radially from the roller carrying portions of the carriers and thus operate as stops to limit the movement oit' the tool into a boiler tube T, or the like. limit the movement oit the tool is clearly illustrated in F ig. 1 ot the drawings.

In the arrangement provided by this invention, the inner ends ot the roller carrying sockets 16 terminate at or in the recesses 2l so that the lugs 22 are at the inner ends of the sockets to hold the rollers in the sockets when the tool is assembled as shown throughout the drawings.

lln using the tool, it is ar 'anged in operating position in 'the boiler tube T with the various parts retracted, as shown in Figs. 2 and 3 oit the drawings. Tt is to be noted that the tool, when in this position, is eom paratively small in diameter, being sutliciently small to treely pass through a hole that will pass the tube T. l/Vhen the tool is in place in the tube T, it is operated through the medium oit the mandrel lil so that the rollers 11 are expanded radially. into pressure engagen'lent with the interior oit the tube T. is the mandrel 14 is rotated in the manner common to devices olf this character, the rollers 11 operate on or roll the tube T into the opening 30 provided in the boiler drum .or plate D. itt is to be noted that the con struction provided by this invention allows for a substantial amount of radial movement or expansion of the rollers, making' the tool useful and effective in tubes ot various internal diameters.

Having described only a typical preferred form ol our invention, we do not wish to limit ourselves tothe specic details set Ylorth, but wish to reserve to ourselves any changes or variations that may appear to those skilled in the art or tall within the scope of the following claims.
